    UTEC Survey completes infield AUV inspection

    Projects and Operations // August 28, 2014

    UTEC Survey Australia Pty Ltd has completed an infield inspection of approximately 550km of pipelines and 20 infield structures off the Northwest coast of Australia using two of its Gavia autonomous underwater vehicles (AUVs). The work was completed on behalf of Apache Energy Limited.

    Offshore activity commenced in mid-June and saw UTEC provide two of its latest model Gavia AUV systems equipped with a full suite of survey sensors. Survey works were carried out from the vessel Yardie Creek, with the scope of work completed in less than four weeks.

    For the first time UTEC operated two AUVs on a ‘back-to-back’ basis – when one system returned from a mission, the next one was ready to go immediately. In some cases the operational up-time in a given day was improved by as much as 40 per cent through the ‘back-to-back’ use of the AUVs. 

    UTEC Australia General Manager Simon Hird commented: “AUVs are a developing technology. Our AUV Centre of Excellence in Houston is constantly striving to deliver new and improved capabilities, some of which were applied on the Apache project. The quality of data gathered and presented from an AUV survey is astonishing in terms of visible detail.”
